What is a hangover?

Alcohol is a poison. It can kill pretty much anything in big enough quantities – which is why it can be used as a disinfectant because it kills bacteria.

After all, the loss of inhibitions, and feelings of euphoria may make you better at busting out your moves on the dance floor, but it also reduces your brain's perception or danger – and ability to avoid it.

The jury's still out on the categorical reasons why you experience a hangover – some people don't and others have different symptoms. But essentially it's your body working overtime to flush out the intoxicant, and drug withdrawal.

Why is all of this happening to me?

You've messed up your internal filtering system.

Your liver is your biggest organ and perhaps, after your heart, and brain, your most important. It does so many amazing things at once: a factory, recycling plant, storage depot and waste disposal facility in one tightly pack 3kg organ.

Part of its job is to filter out and make safe alcohol, which it does quite happily on a rate of one unit per hour. Any more, it starts to struggle, things slip through the net as it tries to prioritise its constant juggling – and you get drunk.

The morning after, your liver is still trying to sort out all the work you've given it to do, but the damage is already done: the toxins are in your blood stream.

Don't worry. It'll forgive you and get it all sorted, it's a pretty good egg like that.

Welcome to the business district. This is a very busy and delicate part of our body where most of our food gets digested.

This tank and pipe construction is one very long tube compacted just beneath our ribs, which mashes, squeezes, dissolves and sucks up all the useful stuff and bins off the bad stuff in a conveyer belt which ultimately ends up in the toilet.

Your brain itself can't feel pain. But it is in a wet, oozy sack inside your skull – called the meninges – which can.

When you're dehydrated the layers of your brain-sack squish together, stretching out the pain receptors in them: cue headache.

Why am I thirsty, why is my face puffy, and why am I dehydrated?

Your kidneys are a built-in water park, responsible for cleaning your blood and keeping you fresh. They also helpfully selectively recycle water back into your bloodstream, keeping you moist.

But the problem with alcohol is it paralyzes the channels which reabsorb the water back into the blood. Instead, everything, good and bad, carries on to the bladder. That's why you need to wee more on a night out – and you get dehydrated so quickly.

So, what can I do about my hangover?

Unfortunately, there is no real cure for hangovers, according to NHS choices- which advises that the best cure is to avoid having one altogether.

However, it does say that there are ways to ease the symptoms of hangovers and the first step involves rehydrating the body so it can deal with the painful symptoms.

NHS choices also says over-the-counter painkillers can help with headaches and muscle cramps. It says: "Paracetamol-based remedies are usually preferable, as aspirin may further irritate the stomach and increase nausea and sickness.

"Sugary foods may help you feel less trembly. In some cases, an antacid may be needed to settle your stomach first. Bouillon soup, a thin vegetable-based broth, is a good source of vitamins and minerals, which can top up depleted resources. Its main advantage is it's easy for a fragile stomach to digest."

It added: "You can replace lost fluids by drinking bland liquids that are easy on the digestive system, such as water, soda water and isotonic drinks (available in most shops).

"'Hair of the dog' – drinking more alcohol – does not help. Drinking in the morning is a risky habit, and you may simply be delaying the appearance of symptoms until the alcohol wears off again.

"If you've had a heavy drinking episode, hangover or not, doctors advise that you wait at least 48 hours before drinking any more alcohol to give your body tissues time to recover. Sometimes, of course, a hangover makes that advice easier to follow."
